The Oregon licensing division does not publish a list of subjects covered in the exam like many other states. The button below will open a basic exam content study guide we have created to help you navigate the many references listed in the allowed books:
Authorized to plan, lay out, supervise, and be responsible for electrical work within the scope of a specific limited license category as defined by the Oregon Electrical Specialty Code (OESC). This includes supervising installations, maintenance, and repairs limited to the systems and environments covered by that license classification.
Ensures that all work within their scope complies with the NEC, Oregon amendments, and applicable laws and rules. They may interpret plans, oversee personnel, and are responsible for code compliance within the boundaries of their limited license.
This license allows supervisory authority only within the defined limited category and does not permit supervision or responsibility for electrical work outside that specific scope.
About reference(s) 8 above. These two books have the same function but there are differences; Reference 8a is more instructional, includes practice questions, explainations and limited calculation help, better for learning the code. Reference 8b has more dense/comprehensive indexing and focuses on multiple paths to the same topic, has minimal explanations, better for speed during exams and finding obscure or oddly-worded questions. We advise buying one or the other based on your needs and the info provided here.
NOTICE: OAR 918 references the National Electrical Safety Code (NESC). You do not need to study this code because it only applies to utility work.
